The ongoing coronavirus outbreak has driven demand for surgical masks sky-high across the globe. In Taiwan, as in other parts of the world, supplies are still short. But while in some countries the idea of wearing a mask in public is something radically novel, in Taiwan, it’s completely unremarkable. Here, people have been wearing masks since well before the outbreak began- a whole century before, to be exact. With masks on everyone’s mind, the National Museum of Taiwan History has put together a mini-exhibit on its Facebook page that shows how masks have evolved and how Taiwan's society has changed over the past 100 years. The museum's Su Feng-nan joins us for a history of Taiwan in masks.
